Education Medical physics graduate students Medical physics residents Medical physics PostDocs Medical residents Beta site Site visitors New version/feature trials Clinical Research Phantom study Patient research Special Requirement Not for clinical use No or limited service support Full functionality New technique trials Mimic/use real clinical environment Some degree of isolation from clinical Access requirement Large number of users Simultaneous access in limited time Error prevention Crash frequently Typical Setup Vendor supplied the research/education only workstations Typically single workstation/server setup Full functionality No clinical patients can be planned and treated Dedicated partial isolation from clinical use institution/department/patients level commissioned machine level Mixed use Same commissioned machine Separate plan/trials or course/plans User management Generic account Easy to manage Dedicated user for students Student can easily share Individual account Take time to manage users Especially disable user after graduation Student still can access other’s plan Test Plan Plan starting point Dicom Image + Contours Partially finished plan Plan Evaluation Reference plan Dose constraint Evaluation discussion Clean up Delete interim/non-ideal test plan Delete all plans after graduation Disable account or delete account Backup and Recovery Dedicated system System backup after upgrade Sample patient, plan or imaging data User plan can be deleted after completion Eclipse, clone the whole disk after setup Pinnacle, ufsdump/ufsrestore also works User should be responsible backup own plans Shared system System backup as part of clinical use only sample patient, plan or imaging data need to backup separately from clinical one User test plan should not be included in clinical backup, individual plan backup can be done be user. Upgrade Dedicated system Typically install fresh new system Restore the commissioned machines Restore the sample patients as needed Shared system Test if the backup can be restored to new version Finish clinical upgrade first Create required isolation Restore the machine and sample patient as needed Patient Data Sharing Non-clinical to clinical Not supported Clinical to non-clinical Anonymize might be needed Same system different version Eclipse Pinnacle Different system Pinnacle to Eclipse Eclipse to Pinnacle BrainLab to Pinnacle Same institution Redundancy reduction Different institution HAPPA issue Protocol and Template Sharing Pinnacle Protocol is a group of script, Can be copied, edited and loaded Eclipse Template is xml file Can be exported and imported Be aware of version difference, always double check. Why do physicists need planning training? When short of dosimetrist staff Emergency case without dosimetrist support Difficult cases that dosimetrist have not time to handle New program setup Plan check/Chart Check Some junior physicist position with job duty as planner Graduate Student Training Steps Didactic Lecture Planning principles Beam setup for comformality and gradient Dose algorithms Optimization algorithms Planning process Imaging, contour, Rx, plan, evaluation Typical approach for disease site Bilateral whole head, Tangential breast, CSI, etc Hand-on lab TPS operation Sample patient for typical disease sites HDR/SRS/TBI/TSEI planning? Commissioning ? Physics Resident Training Steps Phantom study --- find the TPS planning options and limitations TG-119 test case RTOG dry run case RTOG phantom study Typical training test case --- clinical planning skill Sequence: prostate, lung, brain, breast, head&neck Case number: how many is enough? planning need to consider simulation and treatment Uncommon training test case --- experience to handle difficult cases Metal artifact: like prosthesis, breast expander, dental filling Simulation mistake: arm in beam, non-bladder control, object on patient Dose limiting: pacemaker/ICD, fetus, gonad Electron: small field, large oblique, extended SSD, backscatter for keloid Breast: Flash, breast expander Nose/extremities: water, rice, bolus Real life patient plan --- under pressure Simulation error Non-ideal image quality Non-realistic contour Time pressure Compromise of coverage and OAR Interaction with MD Projects development --- integrated process New program setup New patient specific QA device RTOG protocol accreditation Physics Resident Training Steps Phantom study --- find the TPS planning options and limitations TG-119 test case RTOG phantom planning RTOG dry run case Typical training test case --- clinical planning skill Sequence: prostate, lung, brain, breast, head&neck Case number: how many is enough? planning need to consider simulation and treatment Physics Resident Training Steps Uncommon training test case --- experience to handle unusual cases Metal artifact: like prosthesis, breast expander, dental filling Dose limiting: pacemaker/ICD, fetus, gonad Electron: small field, large oblique angle, extended SSD, backscatter for keloid Breast: Flash, breast expander Nose/extremities: water, rice, bolus Simulation mistake: arm in beam, non-bladder control, object on patient, accessory/setup error Treatment consideration: couch kick clearance, electron cone clearance, couch side rail/bar, gantry angle sorting Physics Resident Training Steps What is the bright object? Pacemaker. AAPM TG-34, Management of Radiation Oncology Patients with Implanted Cardiac Pacemakers Physics Resident Training Steps What is the bright object? Prosthesis. AAPM TG-63; Dosimetric considerations for patients with HIP prostheses undergoing pelvic irradiation. Physics Resident Training Steps What is the extra object on top of abdomen? A bolus slab was put on patient abdomen, and RPM tracking reflector was taped on top. Physics Resident Training Steps What is the dark area? Super stuff bolus?
